More extensive, in the embodiment of this general type, angle [alpha] can be in 15 ° to 45 ° scope, and base diameter can be in 0.007 inch to 0.040 inch scope, and pitch can be in 0.005 inch to 0.090 inch scope.Described double can the arrangement with identical pitch, or arrange with the staggered checkerboard type of identical pitch, or be staggered and/or bunchy with different pitches.Describedly doublely can change into single, multi beam and many rows (for example, three or four staggered rows).
The described layout that has been found that bristle is effective for carrying out eyelashes lengthening function.Layout that substitutes and configuration (for example, comprising the cone shape of eliminating bristle) can be used to carry out other such as the reinforcing of eyelashes with function such as separate.
Exemplary but nonrestrictive within the scope of the present invention alternative arrangement and configuration is included in the additional embodiment of the mascara brush of the present invention shown in Figure 10-32.Be similar to Fig. 5-9B, each of these brushes comprises flexible injection plastic main body, this main body comprises and originally is the cylindric nuclear core 12 of the extension of the long geometrical axis of linear, near-end 14 and far-end 16 and a plurality of bristle or fiber, described bristle or fiber 18 are outwards outstanding from nuclear core side direction (nuclear wire mandrel laterally) on the major part of the nuclear core length of nuclear core far-end North Korea nuclear core near-end, and the near-end of nuclear core forms handle 20.The brush of Figure 10-32 also is similar to the brush of Fig. 5-9B, is not shown to have shape and keeps wire rod, but also can be provided with such wire rod.Therefore, the brush in the embodiment of Figure 10-32 only is different from the brush of Fig. 5-9B basically about the feature of the layout of described array of bristles and/or configuration.
Particularly, Figure 10-12 illustrates by a plurality of and is generally the brush 80 that conical bristle 82 forms, described bristle 82 be arranged in a different manner be parallel to all that the major axis of examining core 12 extends single 84 and double 86.Bristle lengths among the row gradually changes along the length of nuclear core, makes bristle tips work in coordination with and defines the abstract envelope (for example being generally the envelope of circular cross-section all the time) that originally diameter increases, reduces then and then increase to proximal direction along the far-end from array of bristles.That is to say, described envelope or brush profile near the 88a place, position of described nuclear core far-end be narrow, broaden at 88b place, first centre position, narrow down once more and broaden once more at the near-end 88d of described array at 88c place, second centre position, and between these minimums and maximum substantially smoothly and variation constantly.
In the brush 100 of Figure 16-18, as in some traditional mascara brush, had by the abstract envelope that the tip limited that is generally conical molded bristle 102 and to be generally columned proximal part 104a and to be generally conical distal portions 104b, this conical distal portions 104b is tapered from the far-end of circular cylinder shaped portion to nuclear core 12.Bristle is arranged in single 105 and double 106, and this single 105 and double 106 all is parallel to the major axis of examining core; It is nearer that single-row bristle holds together ground than them at the proximal part 104a place of array collection at the distal portions 104b place of array, make in the bristle density of part 104b (the bristle number of the per unit length of nuclear core) greater than bristle density at part 104a, therefore offer the zone of two different bristle density of difference of brush, described two zones are provided with before and after the length direction of nuclear core.
The brush 110 of Figure 19-21 also is subregional brush.It is arranged in the major axis that all is parallel to brush single 114 and double 116 in the length (in each row) of bristle 112 reduce gradually to near-end and distal direction from the core 118a of array of bristles, make their tip define near-end and the tapered abstract envelope of far-end to array.In each was single, bristle collects to hold together ground at core 118a place than them at distal portions 118b or at proximal part 118c place nearer; Therefore, brush has the central area (part 118a) of higher bristle density and big envelope diameter, and this central area is arranged between the far field and near region 118b and 118c of the envelope diameter that hangs down bristle density and reduce.
In the brush 120 of Figure 22-24, molded bristle 122 be arranged on once more along the brush length direction extend single 124 and double 126 in, and to pass through can be essentially identical to the interval between the bristle in arbitrary given row.In a row or multi-row on a side of brush, bristle lengths reduces to center 128a gradually from the near-end and the far-end of array of bristles, in center 128a place bristle lengths minimum, make the profile minimum of the array of bristles on this side of brush, and in a row or multi-row on the opposite side of brush, bristle lengths increases to center 128b gradually from the near-end and the far-end of array of bristles, in center 128b place bristle lengths maximum, causes the convex of brush in the aftermentioned side.Bristle lengths among the row between these both sides from brush as identical with end to end shown in the 128d at 128c.
The brush 130 of Figure 25-29 has molded bristle 132, molded bristle 132 similarly be arranged on along the brush length direction extend single 134 and double 136 in, has essentially identical interval between the bristle that in arbitrary given row, passes through, though double bristle is nearer than single-row bristle each interval.The far-end of the bristle lengths North Korea nuclear core at the distal portions 138a place of array of bristles reduces gradually, but in the remainder of brush length, different rows' bristle lengths changes by different way.Therefore, in row 138b, the core towards brush length reduces the length of bristle gradually from part 138a, and bristle lengths increases gradually towards the near-end of array then, and the inverse variation of length takes place in row 138c, and in row 138d except in part 138a bristle lengths identical.Therefore, cause the array of bristles complex outline.As at Figure 28 and 29 the most clearly visible, this profile can be characterized by peanut-shaped.
Figure 30-32 illustrates brush 140, and this brush 140 comprises the vertical row of the bunchy of the bristle 144 that the vertical row of the bigger bristle of single diameter 142 and diameter are less, and in the relative both sides of brush, bristle 144 inserts between the bigger bristle of diameters.In addition, the distal portions 148 by the abstract envelope that bristle tips limited is tapered to far-end 16.
In each of these embodiments, the concrete layout of bristle provides and has been used to transmit, place and the certain benefits of the mascara that distributes, for example with respect to such as combing or add the function of long cilia.
It should be understood that to the invention is not restricted to above feature of specifically illustrating and embodiment, and can be not carried out by the alternate manner from purport of the present invention.
